To all whom it may cooozvn;

Be it known that I, ANTOINE M. Cm'unm'r, a citizen of the Republic of Franco, and a rcsiilent of the city of New York, borough of l /Ianhattan, in the county and State ol? New York, have invented a new and 1m proved internal Cmi'1 ht1ntio|1 Engine, of winch the following L; a full, clear, anti exact descriqtion.

Among the principal objects which the prosent invention has in view are: to provide sliding valves arranged and constrnctoil to avoitl leakage of gas clue to wear of the sliding parts; to provide a simplified constructimi for valves whcrc'oy expansion pressure is relieved therefrom (luring; the movement thereof; to providc a valve meniher simple, (lurahle and cconomionl in constrmction; to provide a simplified valve on crating mechanism; and to provide. a valve operating mechanism embodying a single cam and simialiiietl transmiss-iion mechanism connected therewith.

"Ono en'il'ioclimcnt of the present invention is dissclosetl in the structure illustrated in the accompanying drawings, in which like characters of reference denote corrcsiionrling ports innll the views, zinrl in "whic Figure 1 is :1 'vorlxical section of an internal combustion engine constructecl anal arranged in accordance with the prof-sent invention, the it-)Qllfffl being taken on the line 1--1 in Fig. 3; Fig. 2 is a vertical section of the upper entl of the cylinder of an internal combustion c inc, tho Friffjliflll lining taken on the lino 2 i. in Fig. 3; Flor. 3 is a croes e-ection taken on the line 3 6 in Fig. l, tho valve Jlntc raised to cancel: the cxhxulqt ports of tie engine; Fig. 'iis :1 vcrticnl sec tion. on an enlarged scale, chiming the port ring and thc cylinder walls adjacent thereto; Fig. is :1 vertical section ct an internal combustion engine, lukenon the lino 5-5 in Fig. 7, showing a ioozlilietl form of 11 valve plate conetructcrl and arranged in accortiance with. the pit-sent invention, and moans for operating; the some shown in DlI-Qlllt lll to (Kl'iflfitl the exhaust port on Saul engine; Fig. i) is a verticul'section, taken on the line ti -6 in Fig. 7. of tho np icr portion of an engine conslrn -tcll as in Fig. .1. showing the valve casing: liiterl to PXPUHP the intnho port on with engine; Fig. T a cross; section Shown in the drawings, to form Water and upper oectioms 18 and 19, edges taken on the line 7 in Fig. 5;,Fig. 8 is a detail view, on an enlarged scale, of the valve rin em loyetl in the modified form illustratei in igs. 5 to 7"inclusive; Fig. 9 1s a vertical section, taken on the line 9--9 in Fig. 10, of a modified form of the invention, showing the valve plate in closod relation to both the intake and exhaust ports; 1* 1g. 10 is a cross section taken on the line 10---10 in F 1g. 9; Fig. 11 is a (lctail view of a valve ring constructed as shown in Fig. 5, mid rin being straightened to show the relation 0t tho port openings; Fig. 12 is a vertical section taken on the line l21.2 in Fig. 13, showing a modified form of the invention; and Fig. 13 is a cross sooti'ontalien on the line 13-43 in Fig. 12.

As shown in the ntwoinpanyin" dTfiWill"S, and more particularlv in Figs. fto 4 inc usivo thereof, the olintleris constructed in two scctiono l8 am' 19.. The sections 18 and ill are provided with water jacket spaces 520, I

The meeting edges of the sections '18 and it) anal 21 are huitably machinoii, curved and tenoned, as tight annular fittings tor uniting the three sections, The space- 22 formed between the inner and outer walls of the section 21 constitutcs a continuation of the water jacket for the cylinder, and is in 0 on communication with "the jacket space, 52 ,20 of the lower Between the of tho inner walls B l--84 of the sec tions 18 and 19, mounted a port ring 525.

When the valve ring 28 is lifted the intake ports 36 are disposed in positivs relation to the ports 31.. When the valve ring is depressed to. its lowermost position the huust portsfifi are disposed opposite the ports 32. Intermediate the two position and as shown in Figs. 1 and 2, the ports 31 and 32 are closed by the middle section. of the valve ring 28'.
